ing of the bolt, or upon the back of the slotted y plate on the'upper sash. The tail end of thebolt is formed withaknob orhandle, bywhich it can be turned and moved backward or forward, as above described. If the plate which 55 issecure'd to the upper sash is made a few Ainches in height, asecond slot may be formed in the upper part of the. plate. This would allow ofthe windows being locked when partly opened.v 'Ihe bolt-fastener might also be made 6o vso as automatically to fasten the'sashes whenever they were closed. To effect this the bolt might be thrust forward by aspring, andwhen `drawn back the bolt might be held from being .thrust forward by thespring by its guide-pin ,being `turned into a small vertical slot branching out from. the rear end of the horizontal guide-slot in the casing. When the sashes fwere closed, a part of the fastener carried by the upper sash might strike against the head of the boltfanditurn the bolt,so asto withdraw Y the guide-pin from thesmall vertical branch Y To all whom it may concern:

Be it known that 1,' EDWIN'ROBERT WETH- ERED, a subject of the Queen of Great Britain, residing at Woolwich, in theV countyofV Kent, 5 England, have invented new and useful Improvemcnts in Window-Sash Fastenings, (for which I'have obtained a patent in GrreatBrit-v ain, No. 119, dated January 9,1882, sealed May 23, 1882,) of which the following is a speci- 1o cation. The object of the invention 'is to provide a simple andv efficient" fastening' for Awindow-A sashes, which cannot be opened from the outside, and which, when fastened, will hold the I 5 ',windowls'ashes firmly together. .The part of 'the fastening whichis to be secured to the top railof the lower window-sash carries a bolt somewhat similar to an ordinary `doorbolt,` which can be turnedand slid backward or for- 2; ward horizontally at right angles to the window-sashes. The end of the bolthas a projection or projections standing out sidewise from it, so as to form an oblong head at'its end. The part of the fastening which is Lto be secured to 25 the bottom rail of the upper sash is formed with a metal plate standing up verticallyfrom the rail ofthe window-sash. In this plate is van oblong slot for the end of the bolt before mentioned to pass through. When the bolt is 3o drawn back, a pin projecting from it enters a horizontal slot in the casing within whichy the bolt slides, and the head of the bolt is then in a line with the slot in the plate' carried bythe upper sash. When the bolt is thrust forward slot. The spring would then press the bolt forward and cause it to lock the sashes.

In the drawings hereunto annexed I have shown a sash-fastener formed as above dev scribed. f

At Figure 1, I have shown the two parts of the fastener secured, the one to the bottom rail of the upperrwindowsash and the other to the top rail ofthe lower window-sash. In this figure the two parts of the fastener are shown to be locked together. Fig. 2is a similar view of the fastener unlocked. Figs. 3, 4, andr 5 3 5 to lock the sashes together,the head of theboltV passes through this slot, and when a partial turn is given to the bolt,projecting ends ofthe head come against the back of the plate, and the bolt so is locked. In order that the sashes 4o may be drawn toward one another at the same` time that the bolt is locked, inclines maybe formed at the end of the casingwithin which thebolt slides, for projections at the tail end of the bolt to dbear against. In this way theY 4 5 bolt, as it isturned after being pushed forward, will alsobe somewhat drawn backward, and

as the head of the bolt then bears against the 4back of the slotted plate in the upper sash the two sashes will be drawn together, yor the in- 5o eline might be at some other part of the casshow a plan, sideV view, and end view of the A85 locking-bolt and the casing which carries it. Figs. 6, 7, and 8 show a side view, end View, and plan of the other part of the fastener.V K The'pasing carrying the locking-bolt (shown at Figs. 3, 4, and 5) is fixed to the top rail of 9o the lower sash,while the other part ofthefastener (shown at Figs. 6, 7, and 8) is fixed to the bottom rail of the top sash. In the drawings the bolt is shown as pressed forwardby a spring, so that it may always be ready to lock thewindow automatically whenever the window is closed. Y

A is the casing containingthe locking-bolt. B. is the locking-bolt. It passes through holes in the ends of the casing, and canbeslid foo endwise through these holes, and also turned in them. At one end it is provided with a handle, B', by which it can be turned .and drawn backward. At the opposite end it is formed into a T-shaped head, B2. The stem of the bolt is shown to be surrounded byacoiled spring, C, which tends to thrust the bolt forward.

D is a pin projecting outward from the bolt B. It enters a slot, E, cut in the casing A. One portion of the slot is made longitudinally of the casing. \Vhen the pin projecting from the bolt is in this portion of the slot, the head of the bolt is horizontal andin position to pass through the slot in the other part of the fastener. of the slot is a transverse slot, which allows oi' the bolt being turned at eitherend of its traverse. Then the bolt is drawn back and turned so that its pin D enters the transverse slot E,the bolt is retained in its backward position and cannotbethru st forward by the spring. The head of the bolt is then in an inclined position. Vhen the lower sash is pulled down to shut it, the Alower arm of the T lug or head of the bolt (which head is then by means of the pin D and the short slot E standing at an ineline or angle, as seen in Fig. 5) strikes against the ledge or striking plate or part g of the keeper, as shown in Fig. 2. and the bolt is thereby automatically turned on its axis,so as l to change the Thead from its inclined position to a horizontal one, and when thus brought to this position it immediately, by force of lthe spring, is thrust forward through the opening in the keeper, thus automatically locking the window whenever the latter is closed. By then turning the bolt so that the pin D passes At each end of the longitudinal portionA into the transverse slot 'Ethe two sa'shes will be drawn together, as the two arms of the head ofthe holt then act against `inclined surfaces Gr G, formed above and below the slot in the portion of the fastener which is fixed to the upper sash, and through which thehead of the bolt is passed. The construction of the part of the fastener which is fixed to the upper sash is clearly shown at Figs. (l, 7, and 8.

In place of the handle B being at the rear 'end of the bolt, the pin D might be prolonged outward and formed into a handle.` A cord might also be connected to the handle, so that the bolt might be drawn back and the window unfastened by pulling upon the cord.

Vhen the sash-fasteners are not required to be made self-fastening, they inight be made without the spring C for thrusting the bolt forward. rIhe transverse slot E in the boltcasing would then not be required.

I do not cla-im, broadly, a spring to project the bolt forward, nor a T-shaped head on a bolt; but

I claim- 'In a saslrfastelier, a T-headed spring-bolt on the lower sash, held back by apin and slot,

and arranged to project slightly over the sash when held back, with the T-head at an in' eline, as set forth, combined with a keeper having aledge or striking-plate, g', which on shutting the window acts on this inclined head and automatically causes the turning of the bolt on its axis, releases the pin, and permits the shooting forward of the boltinto its keeper.
